I can see with the impending release of the Google payment system, a lot of people are going to be discussing the release of a serious competitor to paypal. I'd recommend you lead the way and create a section for "GBuy" under the "Google" selection of boards.. theres already some content on this subject being discussed in the other google boards.. fill it up with a few starter threads..
If it gets to the point where there are enough Gbuy threads to warrant a new forum, it will be created (and they will be moved to it), but right now it doesn't seem like there is...
Supply and demand both are interrelated.....In any case its a nice suggestion shawn...just like paypal we should have a section for same...
